TIMOTHY-CLEANING ATTACHMENT FOR GRAIN-SEPARTORS.

SPECIFICATION forming part of Letters Patent No. 597,459, dated January 18, 1898. Application iiled January 18, 1897. Serial No. 619,628. (No model.)

To all whom t may concern.-

Be it known that I, EZRA G. CLYMANS, a citizen of the United States, .residing at Vifaynesborough, in the county of Franklin and State of Pennsylvania, have invented cer- Vtain new and useful Improvements in Timothy-Cleaning Attachments for Grain-Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to attachments to the grain-cleaning devices of separatorsv or threshing-machines for the purpose of adapt-I ing them to clean timothy, fiaxseed, or other small seeds.

This invention consists in the novel construction and combination of the parts hereinafter fully described and claimed.

This invention is an improvement upon the devices for Which a patent, No. 537,602, Was issued on April lf3, 1895.

In the drawings, Figure 1 is a longitudinal section through the grain-cleanin g devices of a separator, showing the timothy-cleaning attachments in position. Fig. 2 is a plan view showing portions of the same.

The timothyfcleaning attachments may be applied to many other grain-cleaning devices besides those shown. A is an inclined board, which conducts the grain and other material to the cleaning devices. A blast of air is forced through the cleaning devices in the direction of the straight arrows. B is a portion of the casing of aseparator. Upper and lower grooved cleaningrolls b and b are jonrnaled in the sides of the casing B, and B are toothed Whe-els operating to revolve the said rolls in the saine direction. C are two side plates supported in the casing B. D, E, and Gr are three grain-plates supported by the side plates C, one above the other in the form of steps, and provided with iiuted plates at ,their rear edges. K is the main gather-board, which catches the grain which falls from the grain-plates and delivers it into a grain-spout (not shown) at lthe lower end of the gatherboard. N is a shakin g-shoe supported in the casing, and .I is the tailingsspont in front of the shoe N and below and behind the grain-plate G. The gatheiboard K and the shoe N are shaken longitudinally by means of eccentrics fm on the stacker-shaft N and suitableintermediate connections. Allthese 5 5 devices are used in cleaning grain and are not a part of the present invention.

In order to clean timothy or other small seeds, brackets 2 are secured to the top of the shoe N, one on each side. A shakingscreen 3 is arranged in an inclined position, With its front and upper end o in a position to receive the seed from the board A. The end o may be supported under the top grainplate D, as shown, or it may come above the top grain-plate and under the board A. It is not material Whether the screen 3 is placed above or below the cleaning-roll b, so long as it receives the seed and other material which slides down the board A. The screen 3 is 7o shaken longitudinally by attaching its lower end to the pins 4: on the brackets 2, carried by the shoe N; but the screen 3 may be shaken in any other Vapproved mannerfor instance, its upper end can be connected to the board A when the said board receives a longitudinally-reciprocating motion. The upper end of the screen 3 is supported on the guides 5 orin any other equivalent manner.

A secondand finer shaking-screen G is snp 8o ported under the screen 3. The rear end of the screen 6 is pivoted to the brackets 2 by the pins 7 and its front end rests on any approved support-as, for instance, the lowest grainplate G. A gather-board S is attached 85 to the rear end of the screen G, over the tailings-spout J, and conducts the seeds which fall through the screen 6 onto the inain gatherboard K. The screen G may be shaken lon gitudinally in any other approved manner. A 9o tailings-board 9 is pivoted at its upper end by pins l0 to the brackets :2. This board 9 is adjustable in inclination, and its lower part is supported by the th uuib-screws 1l, which pass through slots in brackets 12, secured to the board 9, and engage with thebrackets 2. The tailings-board 9 is extensible, being provided With a slidable extension-piece 13 at its upper part, and I4 are bolts Which slide in slots 15 in the board 9 and secure the extension-piece loo in position when tightened up. A tailingsscreen 16 is hinged at one end to the lower end tailings-board, the inclination of which is slide down the tailings-board into the tailingsspout, and the coarse rubbish is discharged onto the shoe N. The inclination of the tailings-screen 16 is adjusted, to adapt it to different materials, by means of the extensible changed to suit the position of the extensionpece. l 16 always rests on the extensible tailingsboard Whatever adjustments may be made to these parts, the blast of air from the fan isA always directed upward by the tailings-board through the slats of the tailings-screen vand g' never passes between the said board andi screen.v The seeds which pass through the? screen 3 are rescreened by the finer screen 6,

and any rubbish mixed with them is taken out and discharged into the tailings-spout.

What I claim is l. In a timothy-cleaner, the combination, with a reciprocatory shoe provided with brackets on its upper side, of an adjustable tailings-board'connected at its upper 'end by As the rear end of the tailings-screen 1 pivots to the said bracketsand provided with a slidable extension-piece projecting above the said pivots, a screen having its rear end pivoted to the said brackets, and a tailingsscreen hinged to the said screen and resting on the said extension-piece, substantially as set forth.

2. In a timothy-cleaner, the combination, with a reciprocatory shoe provided with brackets on its upper side, of an adjustable tailings-board connected at its upper end by pivots to the said brackets and provided with a slidable extension-piece projecting above the said pivots, an upperv screen having its -rear end pivoted to the said brackets, a tailings-screen hinged to the said upper screen and resting on the said extensionpiece,a lower screen arranged under the rear part of the upper screen and having its rear end pivoted to the said brackets, and a forwardly and down wardly inclined gather-board secured to the rear part of the said lower screen, substantially as set forth.

y In testimony whereof I affix my signature in presence of two witnesses.
